Abstract
Laser diodes emitting at 2.36 mu m at room temperature have been fabri cated from a type-II quantum-well heterostructure with an active regio n consisting of five Ga0.65In0.35As0.15Sb0.85 wells and GaSb barriers. A pulsed threshold current density of 305 A/cm(2) has been obtained f or an 820 mu m-long-device at 23 degrees C. The characteristic tempera ture T-0 was found to be 55K between -30 and 50 degrees C, the differe ntial quantum efficiency being 35% for 600 mu m long lasers.
